Expose information about if an event is handled to the backends.
This will allow a backend to deal with unhandled events, such as
macOS' default key bindings.
The first time this function is called, has_xdg_output() returns
true, but haven't yet received all the xdg-output events, so wait
for that to be done. Otherwise, the logical size is 0, and nothing
useful comes from that.
This fixes a problem that is apparent in
https://bugzilla.mozilla.org/show_bug.cgi?id=1869724, but that also
reproduces on any GTK application as described in
https://bugzilla.mozilla.org/show_bug.cgi?id=1869724#c16.
xdg_output sizes might be physical if the compositor doesn't scale them,
it seems. So to report the correct logical geometry in GDK pixels, we
need to detect this case. We do this by checking whether the wl_output
size matches the xdg_output size.
According to the Mesa developers, the correct way to determine
disjointness is to check the actual inode of the fd because dup()ing can
cause these duplications to happen when planes are carelessly copied or
when planes are sent over dbus or other unix sockets.

We keep various pieces of double-buffered state on our side,
and then explicitly sync it over to the Wayland side.
Add a function to find out if we have any.
The ngl renderer has good support for fractional scaling, so we
can enable this by default now.
If you are using the gl renderer, you can disable fractional
scaling with the
GDK_DEBUG=gl-no-fractional
environment variable.
When a toplevel is focused programmatically and there is no
underlying seat, we cannot attempt to focus it with no
focus to be obtained, nor serials serials to use.

In GLES, BGRA is still done by GL_EXT_texture_format_BGRA8888 which is
an extension that is older than GLES 2.0.
And back then, internal formats had to be specified unsized. And when
that was changed with GLES3, nobody updated the extension.
However, on OpenGL, this extension doesn't exist, and internal formats
need to be sized.
So let's use different internal formats depending on GL version.
Fixes#6333
Whether or not switches include shapes to indicate their ON/OFF
state is currently controlled by the stylesheet (in particular
the HighContrast style).
However there are use cases for both using the HighContrast style
without shapes, and for using shapes with the regular stylesheet,
so follow the newly added "show-status-shapes" setting instead.

For tablet tools if we have NULL cursor, we use the default cursor
instead. This provides us with a tablet cursor when an application never
sets the cursor.
However, on proximity out when we clear said cursor we also
need to toggle off cursor_is_default, otherwise on the next proximity in
we assume we already have a cursor and never update it again.
This leads to an invisible cursor over GTK application when the tablet
tool is brought into proximity over the widget (but not when moving into
the widget from the outside).
Closes: #6312
